TRIGGER MECHANISM.

Specification of Letters Patent.

Patented May 14, 1907.

Application filed December 26,1906. Serial No. 349,541.

To all wit/mt 21!; ntcty concern.-

Be it known that I, FRANK A. DE LAND, a e1t1zen of the United States of America, re-

siding atMemphis, iirthe county oflvlacomb and State of Michigan, have invented certain new and useful Improvements in Trigger Mechanism, of which the following is a specifioation, reference being had therein to the accompanying drawings.

It is the object of the invention to obtain a trigger mechanism for use on a double-barreled gun in which the triggers are more conveniently arranged for rapid operation than in constructions heretofore used, and it is a further object to provide means in this form of trigger mechanism for preventing the simultaneous operation of the triggers WVith these objects in. view, the invention consists primarily in a construction of trigger mechanism wherein the triggers are arranged side by side in substantial parallel alinement, whereby the triggers may be operated by the same finger by a slight change in its angularity so as to bring the pressure to bear upon the one or the other as may be desired.

The invention further consists in a locking mechanism for the triggers, preferably in the form of an oscillating member, the operation of which is controlled by the triggers, and which serves, upon the operation of either trigger, to automatically arrest the other from movement, all as more fully hereinafter set forth and described.

In the drawings, Figure 1 is a perspective view of a portion of the trigger plate to which the trigger mechanism is attached; Fig. 2 is a horizontal section through the trigger locking mechanism; and Fig. 3 is a vertical section therethrough.

A is the trigger plate, and B is a triggerguard secured thereto.

G and C are two triggers, which are arranged side by side within the guard B.

To prevent the simultaneous firing of both barrels, a locking means is provided, which permits either one of the triggers to be freely operated, but prevents simultaneous operation of both, the construction being preferably as follows:

D and D are parallel. plates attached respectively to the triggers G and C, and projecting within the frame of the gun through slots in the portion A.

E is the pivot for the triggers at one end of the plates D and D, and at their opposite ends these plates are cut away at F and F to form opposed should rs G II. I

I is an antifriction roll, preferably of frustoconical form, and. journaled upon a pin J secured to a swivel-post K. This roll is normally arranged in the central plane between the plates D and D, and projects oppositely over each of the shoulders G and H, being yieldingly held in this position by a spring L engaging the post K. The arrangement is such that the raising of either one of the plates D and I). by the movement of its trigger, will cause the shoulder G, or H, to bear against one side of the conical roll, and deflect it laterally. This lateral deflection will, however, move the roll completely above the shoulder of the other plate, so as to lock the latter from movement. On the other hand, if both of the triggers are pulled simultaneously, the pressure of the shoulders upon opposite sides of the roll will be equal, preventing deflection in either direction, and arresting movement of both plates.

From the foregoing description, it will be seen that the necessity of the operator changing his grip upon the gin stock is entirely obviated, and thus it is possible to obtain superior results. Furthermore, there is no no cessity of moving the hand forward to errgage the front trigger,-as is the case in the usual construction of trigger mechanism, and thus the striking of the lingers of the hand against the trigger-guard during the forward movement of the hand, and the conseqi'ent injury to the linger, is entirely obviated.

IVhile I have shown and described a particular form of locking mechanism to be used in connection with the side by side arrangement of the triggers, which I deem preferable in use in view of its simplicity in construction,-I do not desire to be limited to the same, as various modifications could be employed without in any way departing from the spirit of my invention.

What I claim is my invention is:

1. A trigger mechanism comprising a plurality of independently operable triggers arranged in transverse alinement, and means for preventing the simultaneous operation of said triggers.

2. A trigger mechanism comprising a plu rality of tri gers arranged in transverse alinement, para lel plates connected respectively to said triggers, and a laterally movable member arranged in a plane centrally between said plates, and thereabove, said member eX- tending into the path of movement of each plate, for the purpose described.

3. A trigger mechanism comprising complementary triggers arranged in transverse alinement, and a laterally shiftable member, controlled in its operation by the triggers, locking the latter against simultaneous movement.

4. A trigger mechanism, comprising a plurality of triggers arrangedin transverse alinement, and spring pressed locking means controlled by the triggers acting automatically upon the operation of either trigger to prevent movement of the other.

5. A trigger mechanism, comprising two independently operable triggers arranged in transverse alinement, and a spring pressed oscillating member controlled by the triggers acting upon the operation of either trigger to automatically lock the other against move ment.

6. In a trigger mechanism, the combination of two triggers arranged in transverse alinement, sear plates for the triggers, alining shoulders upon the lates, and a spring pressed laterally shiftab e roller in operative relation to the shoulders.

In testimony whereof I am); my signature in presence of two witnesses.
